BALTIMORE, MARYLAND, A CORPORA- WRINGER HOUSING FOR WASHING MACHINES.

Application filed August 16, 1923. Serial No. 657,658.

To all whom it may conce'm:

Be it known that I, GEORGE. C. HOOKEN- BERGER, a citizen of the UnitedStates, re-

siding at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inWringer Housings for Washing Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same. My invention relates to wringer housings forwashing machines;

Among the objects of my invention are To provide a wringer housing forwash ing machines whichcan be readily machined and readily assembled.

To provide a'wringer housing for washing machines providing for greaterfreedom of movement of the wringer supporting frame so that it may bepositloned in any one I prevent end motion of said pinion.

of a plurality of positions.

To be readily assembled in combination with a center housing arranged tocooperate therewith.

These and further objects of my invention will be set forth in thefollowing specification, reference being had to the accompanying drawingand the novel means by which said objects are effectuated will bedefinitely pointed out in the claims.

In the drawings Figure 1 is a central sectional elevation of my improvedwringer housing.

' in said figure.

Fig. 4 is a view of the parts shown in Fig. 1 looking in the directionof the arrow 4 Fig. 5 is a section along the line 55 in Fig. 1 lookingin the direction of the arrows.

In the drawings represents a portion of a suds contain-' provide awringer housing which can by bolts such as 12 and said casing isprovidedwith a wringer bearing 13 in which the wringer sleeve 14 is revolublymounted.

An index pin 15 is slidably mounted in the casing 11 and pressed towardsthe sleeve 14 by the spring 16, a knob 17 serving to provide means forwithdrawing said pin from index holes such as 18, any desired pluralityof which can be provided in the sleeve 14. The sleeve 14 is providedwith a groove 19 for a purpose hereinafter explained, and is alsoprovided with a shoulder. 20 which rests upon a shoulder at the top ofthe casing 11. I

The sleeve 14 is provided with a pinion bearing2l which is coaxial withthe pinion bearing 22 formed in the casing 11, and bevel pinions 23 and24 are each provided with hubs which are revolubly mounted respec tivelyin said bearings. The hub of the pinion 23 is provided the groove 25 andthe point of the screw 27 enters said groove to The screw 27 is mountedin the sleeve 14.

The pinions 23 and 24 are each provided with square axially disposedholes and the square shaft 29 has itsends mounted in said holes. Pins 30and 31 prevent undue displacement, respectively, upward and downward ofsaid shaft.

A bevel pinion 32 is pro-vided with a hub that is revolubly mounted inthe bearing 33 shaft and located within the slot formed in the hub ofthe pinion 32.

The sleeve 14 is formed integrally with the gear housing 14 at the upperend thereof.

The wringer frame 34 is secured to said gear housing by bolts such as 41and the top of said gear housing is closed by the cover 42. The wringerframe 34 is provided with an extension 43 which is used for the supportof a drip pan or other device for catching the water wrung from theclothes.

,in the casing '11, the shoulder 49 of said bushing fitting snuglyagainst a flat surface formed on said casing. v

The pinion 45 is provided with acentral cylindrical hole in which isloosely mounted the wringer driving shaft 49. a pin 50 Htting tightly insaid shaft and loosely in holes provided in the hub of the pinion 45 toproduce a driving connection between said shaft and said pinion.

Theshaft 49 is driven by the sleeve 51 and the latter is revolublymounted in a bear ing provided in the center housing of thewashing'machine- The center housing being the subject of a patentapplication executed on even date herewith is not completelyillustrated.

The bushing 46 and housing 52 are provided with counterbored recessesfor the reception ofthe shield tube 53, and cork washerssuch as 5454 aremounted between the ends of said tube and said recesses for a purposehereinafter explained.

The manner of assembling my'improved wringer housing is as follows Thecenter housing 52is first secured to the suds container 10 and thesleeve 51 is assembled with the housing 52 as set forth in theapplication for U. S. Letters Patent above referred to. The shaft 49 isthen assembled with the sleeve 51 by driving the pin 54 through theholes in said sleeve into a tightly fitting hole in the shaft 49.

The tube 53 is cut approximately of the proper length and mounted withinthe recesses formed within the bushing 46 and housing 52. The bushing 46is still unasscmbled with the casing 11 and the screws 47 and 55 are notyet in place, the latter hav ing a pin which extends into the groove 56of the sleeve 51 and normally prevents endwise motion of the sleeve 51The casing 11 is then assembled with the bushing 46 and said casing isapplied to the suds container to ascertain if the holes in saidcasing'for the bolts 12 register with the corresponding holes in thesuds container If they do and the tube 53 does not hold the shoulder 49against the corresponding flat surface on the casing 11, then washerssimilar to 54 are to be placed between the tube 53 and the ends of therecesses in the bushing 46 and center housing 52. If the holes in thecasing 11 for the bolts 12 do not register with the corresponding holesin the suds container when the shoulder 49 is against the correspondingsurfaces of said casing, then the tube 53 is to be shortened until saidholes do register.

In either case, when the casing 11 is mounted on the suds container 10,the function of the tube 53 is to hold the shoulder 49 against thecorresponding surface of said casing. After the tube 53 is made of theproper length or the proper number of.

washers 54 for insertion within the recesses has been determined thenthe pin 50 can be driven in the shaft 49 to couple said shaft with thepinion 45. This is accomplished by removing the casing 11 and drawingthe shaft 49 sufiiciently beyond the eirtreme upper surface of thebushing 46 to enable said pin to be so driven. The cork washers 54 alsoact to prevent leakage of oil. 3

After the pin 50 is driven in place the pinion 45 and shaft 49 are moveddownwardly and towards the left, the screw 47 is inserted to hold saidpinion in place and the screw 55 is inserted to hold the sleeve 51 inplace. The casing 11 with the other parts assembled therein can then bebolted in position. The outside diameter of the pinion 45 being smallerthan the diameter of the cylindrical portion 48, it is evident that saidpinion will readily pass through the hole in the casing 11 which fitssaid portion. l

The other parts of the wringer housing are assembled as follows :'Itbeing understood that the casing 11 is not yet assembled with thebushing 46, the hub of the pinion 24 is placed in the bearing 22. Thepinion 24 can be readily assembled as just described through the openingin the casing 11 which is afterwards covered the plate 57. The shaft 29is then placed in the pinion 24. The shaft is placed in the \vringerframe 34'and the pinion 32 is then placed with its hub in the bearing 33and the sides of the slot 40 embracing the pin 39. The screw 35 is thenput in place.

The pinion 23 is passed through the opening which is afterwards closedby the cover 42 and the hub of said pinion is mounted in the bearing 21.The screw 27 is then put in place to keep said pinion from movingendwise. ,The sleeve 14 is then mounted in the bearing 13 and duringthis movement the shaft 29 is guided within the square hole in thepinion 23. The frame 34 is then assembled with the gear housing 14 whichcan readily be efi'ected since the largest diameter of the cylindricalportion 57 on said frame is larger than the largest diameter' of thepinion 32 and said cylindrical portion fits snugly within a holeprovided in the gear housing 14 The pin 15 and its appurtenant parts arethen assembled.

Thus it will be seen that I provide a simple, cheap and eliicientwringer housing which can be assembled with a minimum of effort.
